Months before he was arrested on allegations of mailing bombs to several prominent Democrats, Cesar Sayoc sent threatening messages over Facebook to U.S. Rep. Beto O’Rourke, D-El Paso, a spokesman for O’Rourke’s U.S. Senate campaign confirmed Wednesday.

“We received a threat via Facebook from that individual in April, a threat toward Beto, and we immediately reported it to the [U.S.] Capitol police,” the spokesman, Chris Evans, said in a text message. “Then we turned over the message and the information and the threat to the FBI in July.”

Last week, the FBI sent agents to O’Rourke’s El Paso campaign office to check the mail.

Sayoc faces charges that include interstate transportation of explosives and illegal mailing of explosives. The bombs were sent to the homes or offices of former President Barack Obama, former Vice President Joe Biden, former presidential candidate Hillary Clinton and billionaire George Soros, who has donated to Democratic causes.

Asked about the threats during a campaign stop Wednesday afternoon in Austin, O’Rourke said he was confident Texans would rise above the animosity.

“We just got to continue to do our best to be good to one another, to try to lead by example,” O’Rourke said, recalling a man who greeted O’Rourke earlier in the day in Irving and told him he voted straight-ticket Republican but just wanted to thank O’Rourke for the campaign he is running.

“That’s the Texas spirit,” O’Rourke added. “I feel safe in this state. I feel like we do right and good by one another when given the chance, and we’re going to continue to do that.”

Another possible Texas target was state Rep. Poncho Nevárez, D-Eagle Pass, who told The Texas Tribune on Wednesday that he heard from the FBI this week. On Tuesday morning, he said, agents came to his office in Eagle Pass to inform him that Sayoc had been searching for him online.

“The guy was Googling me, stalking me, trying to find out stuff about me — coming up with my address at the Capitol and at home,” Nevárez said.

Hours later on Tuesday, Nevárez was informed that a suspicious package had been mailed to his office at the Texas Capitol in Austin, resulting in the evacuation of several offices in the building. Law enforcement officials eventually said that “no viable threat was discovered.”

Nevárez said he had no idea why he might have been a target for Sayoc — but the coincidence was eerie. He added that he plans to step up security measures.
